My invention relates to improvements in slicing machines and has for onepurpose the provision of improved means for supporting the slice at thetime of its severing from the body of the work; Another objectis theprovision of improved means for deflecting the slice, away .from theknife wh ch cuts it.

I Another object. is the provision of improved means for deliveringslices cutby the rotary knife to a receiving tray. V

Other objects will-appear from time to t me in thecourse of thespecification and claims.

My invention is illustrated more or less diagrammatically in theaccompanying drawings, wherein:

Figure 1 is a plan View;

Fig. 2 is a rear elevation;

Fig. 3 is a section'on line 33 of F1g. 2;

Fig. 4 is a section on the line 4-4 of F g. 2;

Fig. 5 is a section on the line 55 of Fig. 4;

Fig. 6 is a detail; and

Fig. 7 is a partial horizontal section through a variant form. 1

Referring to the drawings, A generally 1ndicates a base portionupon-which may be mounted in any suitable manner, a motor A with a motorshaft A and a pulley A A indicates a belt extending about a pulley A? onthe knife shaft A. I, y

B indicates a rotaryoknife mounted on the knife shaft A and forwardlyrecessed as at B and rearwardly as at B g V C indicates a guard platemasking a forward face of the knife. The knife is protected from therear by the frameor housing portion C upwardly projecting from the baseA. Formed with or mounted upon this frame portion O is the bearingsleeve C in which the knife shaft A is mounted. This bearing sleeve C isforwardly flared or ex panded as at C to terminate in an arcuate lip Cwhich penetrates the rear recess B of the knife as shown, for example,in Figs. 1, 3, 4 and 7.

1) generally indicates a gauge plate which may be mounted on anysuitable support generally indicated as at D D indicates a rotary knobwhereby, through any suitable gearing or drive means the support DPandgauge plate D may be moved Into and out of and rearwardly away from thecutting plane. Underlying the gauge plate D is a slice support D in theform of an extended bar. This bar includes or has mounted thereon anelevated portion D adjacent the closest approach of the bar to thecutting edge of the, knife. This raised portion D extends upwardly abovethe normal level of the top of I the bar D It is to be seen, as in Fig.4:, that an end of the bar portion projectsinwardly past the peripheryof the knife as at D, this end D being more or less curved or spacedoutwardly away from the rear face .of the knife. Preferably the curvedportion D eX- tends or curves from the cutting edge of the knife,closely approaching the knife at the cutting edge and being spacedlaterally. therefrom an increasing distance progressively toward thecenter ofthe knife. This form of the disposition will be clear from Fig.4. The bar D is also provided with a recess or downwardly and outwardlycut-away and beveled or curved portion D This cut-away portion permitsthe severed slice to clear or drop below the level of the raised portionor supporting abutment D and also deflects the slice away rom the rearface of the knife.

In order to receive the slice after it issevered, I provideany suitablereceiving tray E, the details of which do not of themselves form part ofthe present invention,-but which is formed as at E closely toapproachthe cutting plane. In. order to support the ma-- terial to besliced, I provide any suitablecarriage structure generally indicated asG which rides along the circular supporting rail G and the rectangularguide rail G G G indicate downward projections or tongues from thecarriage structure G which engage also sides of the guide track G as bythe adjustable members G. G indicates a work support positioned upon thecarriage G. Preferably the level of the upper surface of thework supportis substantiallyeven with the top of bar D The member 1) projects abovethe surface of the bar D and also above the surface of the support G Theedgeof H which may be secured as by the screws H to the enlarged portionC3 of the sleeve C Mounted at the outer extremity of the bracket His adeflector generally indicated as H the forward end H of which mayapproach or contact the end of the slice support which is beveled or cutaway as at H adjacent the forward end of the projection D.

It will be realized that whereas I have shown and described a practicaland operat ing device, nevertheless, many changes may be made in size,shape, number and disposition of parts without departing from the spiritof my present invention. I wish my drawings, therefore, and mydescription to be taken as in a broad sense illustrative ordiagrammatic, rather than as limiting me to my particular descriptionand disclosure in detail.

The use and operation of my invention are as follows I find itpreferable to support the slice at the point of severance and anefficient method of supporting it is to employ an upward projection suchas the member D which lies in part-on each side of the cutting plane.This projection D provides a positive support for the work at the pointof severance and for the slice as it is being severed. As soon as theslice is actually severed it should be permitted to drop to clear fromthe rear of the knife.

, This is important in order to prevent adherence of the slice to therear face of the knife. The result of such adherence may be damage to orbreaking up of the slice and bleeding of the material. In order toeffect this free drop and guide action, I have cut away the end of thebar as at D or provide a similar cut-away portions H and H in connectionwith the deflector H The slice, therefore, drops, its edge being free todrop, and engages the cut-away portion D or H This downwardly andoutwardly curved or 'inclined cut-away portion tends to throw the sliceoutwardly away from the knife and it is, in practice, discharged on thetray E an inch or more away from the cutting plane. In order to preventany interference with the slice as it is severed, I find it preferableto form the portion D of the bar D in such fashion that it approachesthe cutting edge only at the cutting point and recedes rapidly therefromas shown in Fig. 4%. This prevents any tendency to wedge or catch theslice or fragments of sausage casings and the like between the knife andthe member I). The

I deflector H is similarly formed and spaced.
